We studied the change in intraocular pressure (IOP) in 15 consecutive cataract patients who underwent extracapsular cataract extraction and posterior chamber lens implantation between Feb. 1993 and Apr. 1993 to evaluate the effect of this surgery on postoperative IOP. To evaluate the clinical usefulness of non-contact tonometer, the intraocular pressures were measured with Kowa non-contact tonometer (TM-2000, Japan) as well as Goldmann applanation tonometer. There was a decrease in IOP of $3.4{\pm}2.9$mmHg (p<0.00l) 3 months after this surgery and the intraocular pressure differences between pseudophakic eyes and contralateral phakic eyes at 3 months postoperatively were $2.4{\pm}3.8$mmHg (p<0.05). The correlation coefficient between non-contact tonometer and Goldmann tonometer was 0.8876 (p=0.001) in the postoperative 76 eyes. Therefore, our results suggest that extracapsular cataract extracion and posterior chamber lens implantation alone can be a useful surgical method in cataract patient with ocular hypertension, and non-contact tonometer was relatively accurate in measuring the postoperative intraocular pressure.

Traumatic bone cyst is a nonodontogenic cyst without epithelial-linig which contains fluid in it's cavity, and it is limited by bone walls with no evidence of infection. Traumatic bone cyst is asymptomatic and appears more frequently in the second decade. Gender distribution is approximately equal, although males are affected slightly often than females. Radiographically the lesion shows a well demarcated radiolucent lesion of variable size and the lesion may have scalloped margins. The adjacent teeth to traumatic bone cyst remains vital. Traumatic bone cyst is usually treated by surgical exploration and currettage of the lesion. In the first case of this case report, the patient was refered from the local dental clinic for the radiolucent area under the left mandibular first molar. From the panorama radiograph at the first visit, the radiolucent area of the left mandible showed a well defined scalloped margin and identified as traumatic bone cyst. In the second case, the patient have visited for the chief complaint of swelling and abcess of right maxillary second premolar. In the radiographic check up with panorama radiograph, the radiolucent lesion with well demarcated scalloped margin was found in the right mandible body, and identified as traumatic bone cyst. In the first case, overinstrumentation was done through the mesial root canal to irrigate the lesion. In the second case, not any treatment was done, and watched the progression of the lesion. And in both cases, after two month, the radiolucency and the size of the lesion has decreased to show healing in progress.

Dentigerous cyst is a cyst arising by tissue fluid accumulation between the enamel and the residual enamel epithelium. It includes the crown of the impacted tooth and excludes the root. The treatments of the dentigerous cyst are enucleation, marsupialization, decompression, surgical excision and etc. In these cases children were evaluated for the chief complaints of the remained mandibular primary second molar. Each cases showed swelling on the buccal side of the primary secondary premolar. In the radiologic evaluation a radiolucent lesion including the crown of the mandibular secondary premolar was found, and it was diagnosed as dentigerous cyst. And the histopathologic examination showed the same result. Marsupialization was operated through alveolar socket and the alveolar socket was protected with vaseline gauze, the obturator combined with space maintainer was followed by the operation. After the operation, the impacted permanent tooth was showing faster eruption speed than the other normal teeth.

In the benign bone tumor such a fibrous dysplasia, destructive lesion is generally treated by curettage and simple bone graft. Such lesions are unlikely to recur if treated local curettage with bone graft or simple excision of the lesion. When it is impossible to cure only with simple bone graft due to wide extent of tumor, vascularized fibular graft have been introduced for functional loss and appearance. The recurrence of the primary tumor in the grafted fibula is rare in benign bone lesion. We experienced a case of fibrous dysplasia which was recurred in the grafted fibula following the initial treatment with vascularized fibular graft. So we report a case of our experience.

A clinical study was done on 24 cases with foreign body in the air passage, who were treated at the department of otolaryngology of Kyung Hee university hospital during the period from Apr. 1973 to Feb. 1983. The obtained results were as follows : 1) The incidence of sex was much higher in male than female and children under 4 years old were predominant. 2) Almost of all patients came in the hospital within 3 days after onset. However one patient came in hospital 5 months later. 3) The variety of foreign body was numerous, among which vegetables and plastic materials were most frequently found. 4) The most common sites of lodgement were trachea and right main bronchus. 5) The common clinical manifestations were dyspnea, decreasing breathing sound and cough. Negative X-ray findings did not exclude a foreign body in the air passage. 6) The important pulmonary complications due to foreign body were atelectasis, emphysema and pneumonia. 7) Foreign body was successfully removed by use of peroral or inferior endoscopy in all cases except one case, on whom thorachotomy was done. 8) The important complications due to the surgical procedure were decannulation difficulty and pneumothorax.

상윤상후두부분적출술은 과거 후두전적출술을 실시하던 환자들에서 선택적으로 사용하여 만족할만한 종양학적 결과 및 후두의 생리적인 기능을 보존 할 수 있어 점차 널리 보급되고. 있다. 이 술식후의 기능변화나 보상기전등에 대하여는 잘 알려지지 않았으나 정상인과 비교하여 음성지표들의 변화가 보고되고 있다. 이 수술은 원발병소의 위치에 따라 CHEP, CHP 방범으로 재건할 수 있으며 종양의 범위에 따라 일측의 피열연골과 윤상연골의 앞부분을 제거하는 extended procedure등이 사용되고 있다. (중략)

인체에서 발견되는 전체 신경초종중 $25{\sim}40%$가 두경부에서 발견되나 경부미주신경의 신경초종은 매우 희귀하여 1988년까지 영문문헌상 88 예가 보고되어 있다. 임상적으로 경부종괴가 주증상이며 때로는 애성, 종괴촉지시 기침 혹은 방사통, parapharyngeal space 의 종괴성장으로 연하곤란등이 초래되기도 한다. 치료는 종괴의 완전적출과 미주신경의 기능을 보존시키는 것이 주요 목표로 되어 있다. 저자들은 최근 5년간 4 예의 정부미주신경외 신경초종을 경험하였는데, 3 예는 측경부의 상부에, 1예는 측경부의 하부에 발생한 것이었다. 연령은 25세에서 50세까지 성인연령이었고, 성별은 남자 l 예, 여자 3 예이었다. 내원시 주소는 전예가 무통성 경부종괴이었으며, 종괴의 크기는 직경 3cm에서 10cm까지 다양하였다. 전예에서 종괴로 인한 신경학적 증상은 없었으나, 1 예에서 parapharyngeal space 의 거대종괴 때문에 다소간의 연하곤란이 있었다. 2 에에서는 종괴촉지시 기침이 유발됨을 호소하였다. 수술은 경부횡절개로 흉쇄유돌근을 제치고 총경 동맥과 내경정맥을 종괴의 상하부위가 완전히 노출되도록 박리한 후 종괴의 피막을 미주 신경의 주행방향에 따라 절개하여 적출 (enucleation) 하였다. 적출술시 종괴가 유착되어 있는 피막 부위는 동시에 절제하되 미주신경의 신경경로 (neural pathway) 는 유지되도록 하였다. 수술직후 2 예에서 일시적 애성을 호소하였다, 추적은 최단 20 개월에서 최장 80 개월까지 하였는데 일시적 애성은 호전되었고 전예가 재발없이 건강하게 지내고 있었다. 따라서 본 종양수술은 종양적출술시 이환된 미주신경의 절단을 결정하기 전에 신경경로를 유지시킬 수 있는 적출술 (enucleation) 을 먼저 고려하는 것이 바람직하다고 사료되었다.
